Why use AGT™ Glow Stones?

Industry Leading Glow Duration

Our AGT™ ULTRA-X Glow products are the latest in a line of state-of-the-art glow-in dark innovations. This time around, we've replaced traditional glowing pigments with an efficient microcrystal that can store and emit light for hours after being exposed to artificial light - aka photoluminescence! AGT™ products can maintain their glow in the dark qualities for 15+ hours. With only 8-10 minutes of exposure to daylight or UV light, they will continue glowing long into the night.


AGT™ Glow Stones are up to 65% brighter than ANY commercial grade glow stones, glow in the dark gravel, glowing pebbles, natural stone glow marble, or glow glass chips commonly available online.

Eco-Friendly & Energy Efficient

All of our products are designed to be environmentally friendly, non-toxic and REACH compliant. The photoluminescent material used in AGT™ products has been proven safe for the environment, humans and pets.


State-of-the-art glow chemistry in the AGT™ Glow Labs has produced waterproof glow in the dark glow pigments that work amazingly well in water-based applications. The glow performance of our glow in the dark sands remain unmatched by common photoluminescent or afterglow pigments.

Energy Saving Solar Power

AGT™ Glow products require no electricity and thus, they do not consume any natural resources. No need for artificial lighting when you have AGT™ ambient lighting in your backyard, park or city path.
